Precise vacuum
These days, it is hard to imagine modern laboratories without controller-operated vacuum pump systems. They deliver precise vacuum and offer widely diverse control functions for a huge range of applications in the laboratory.

Gentle distillation
The SEM 950 vacuum pump system enables reliable manual control over the process in the rotary evaporator. A closed system permits gentle distillation and high rates of recovery even with low-boiling solvents.

Straightforward operation
Power is adjusted by turning a rotary knob to control the speed of the vacuum pump. Parameters are indicated on a display; the membrane keypad makes it easy to intervene in ongoing lab processes with speed and precision. The SEM 950 contains: vacuum pump, valve controller, gas ballast valve, condenser, and separator. Adjustment options: Pressure and pump speed (suction power adjusted with rotary knob, digital vacuum indicator).

Perfectly matched components
This vacuum pump system SEM 950 opens up a whole new range of options in the laboratory. This is due to new functions and technical solutions. Thanks to the coordinated development of the individual components it has been possible, for example, to adjust the sensitivity of the motor to suit the requirements of the control process.

Fast process times
Besides intelligent control, the diaphragm vacuum pump used in the SEM 950 further contributes to short process times. The pump is fitted with the patented KNF diaphragm system that ensures high suction speeds even at low pressures.The vacuum pump system achieves an ultimate vacuum of 2 mbar absolute and delivers up to 50 liters of gas per minute. All gas carrying parts are manufactured from chemical resistant materials.
